write your demo in julia

Different from markdown format demo, source demo files are preprocessed so that it generates:

1. assets such as cover image
2. julia source file
3. mardkown file
4. jupyter notebook file

Links to nbviewer and source files are provided as well.

The conversions from source demo files to other files are mainly handled by Literate. The syntax to control/filter the outputs can be found here

x = 1//3
y = 2//5

2//5

Images can be loaded and displayed

using TestImages
img = testimage("lena")
